英文摘要 | Reversible addition-fragmentation chain transfer polymerization (RAFT) was used to produce well-defined telechelic poly(N-isopropylacrylamide) (PNIPAM) with dibromomaleimide and dithiobenzoate groups at each end of the polymer chain by virtue of the functional RAFT agent 3,4-dibromo-1-(4-cyano-4-(phenylcarbonothioylthio)pentanoic)-2,5-dihydro-1H-pyrrole-2,5-dione. Cyclic PNIPAM was then obtained using an in situ intramolecular bromomaleimide-thiol substitution reaction after NaBH4 reduction of the dithiobenzoate end group to release a thiol group. In this ring-closure process, another bromo substituent on the maleimide group survived, being a single reactive site for post-functionalizing the cyclic PNIPAM by a second bromomaleimide-thiol substitution reaction. After being reacted with 2-aminoethanethiol, the resultant amino-functionalized cyclic PNIPAM was further demonstrated as a building block to construct a tadpole-shaped block copolymer by coupling with linear succinimidyl ester end-functionalized poly(ethylene oxide) based on active ester click chemistry.
